Ginger, long used as a folk remedy for soothing tummy aches, helped tame one of the most dreaded side effects of cancer treatment — nausea from chemotherapy, the first large study to test the herb for this has found.

People who started taking ginger capsules several days before a chemo infusion had fewer and less severe bouts of nausea afterward than others who were given dummy capsules, the federally funded study found.

'We were slightly beside ourselves' to see how much it helped, said study leader Julie Ryan of the University of Rochester in New York.

Results were released Thursday by the American Society of Clinical Oncology and will be presented at the group's annual meeting later this month.

But don't reach for the ginger ale. Many sodas and cookies contain only flavoring — not real ginger, Ryan said. Her study tested a drug-like ginger root extract, and it's not known if people could get the same benefits from ginger teas or the powdered ginger sold as a spice.

Still, ginger capsules may offer a cheap, simple way to fight nausea, which is far more than just a quality-of-life issue, doctors say. Some cancer patients cut treatment short or refuse chemo altogether because of nausea, hurting their chances of beating the disease."
